TELLEZ, Claudio A. y ISHIKAWA, Dilson N.. Infrared and Raman Spectra (Solid State) of Diamminediiodidecadmium (II) Complex with 15N and 2H Isotopic Subtitution. Rev. Soc. Quím. Méx [online]. 2000, vol.44, n.2, pp.139-143. ISSN 0583-7693.
The Raman and infrared spectra of the Cd(NH3)2I2 complex with 15N and 2H substitution have been obtained in the solid state. Based on a normal coordinate treatment as an eleven-body problem, the vibrational spectra were assigned. With exclusion of the ammine torsional vibration, the vibrational modes of the ligand, framework-coupling and skeletal frequencies have been determined. Valence force constants values fCdN and fCdI were compared with the analogous force constants of Cd(NH3)2Cl2 and Cd(NH3)2Br2. The results of the calculations are discussed in terms of the present assignment for Cd(NH3)2I2 and previously reported potential constants for the Cd(NH3)2X2 and Zn(NH3)2X2 (X = Cl, Br, I).
